Jupiter has lots. Mars has some, too, as does Neptune.

In the year 2182 -- 172 years time -- there's a <a href="http://www.universetoday.com/2010/07/27/researchers-say-asteroid-has-1-in-1000-chance-of-hitting-earth-in-2182/">1 in 1000 chance</a> that <a href="http://news.discovery.com/space/future-hazard-1-in-1000-chance-of-asteroid-impact-in-2182.html">we might be hit</a> by a very large asteroid.</a> With two centuries advance notice, will we be able to develop effective <a href="http://news.discovery.com/space/near-earth-asteroid-threat.html">asteroid deflection techniques</a>? <i><blockquote>Asteroid '(101955) 1999 RQ36' is part of the Potentially Hazardous Asteroids (PHA), which have the possibility of hitting the Earth due to the closeness of their orbits, and they may cause damages. This PHA was discovered in 1999 and has around 560 meters in diameter.
<a href="http://www.physorg.com/news199443637.html">In practice, its orbit is well determined thanks to 290 optical observations and 13 radar measurements, but there is a significant "orbital uncertainty" because, besides gravity, its path is influenced by the Yarkovsky effect. Such disturbance slightly modifies the orbits of the Solar System's small objects because, when rotating, they radiate from one side the radiation they take from the sun through the other side.</a>
The research, which has been published in Icarus journal, predicts what could happen in the upcoming years considering this effect. Up to 2060, divergence of the impacting orbits is moderate; between 2060 and 2080 it increases 4 orders of magnitude because the asteroid will approach the Earth in those years; then, it increases again on a slight basis until another approach in 2162, it then decreases, and 2182 is the most likely year for the collision.</blockquote></i>
